How accurate is the 4th gen test duo for hiv, is p24 found in hiv 2?

[james1202]

So i had unprotected anal he did not ejaculate inside me, i had the 4th week duo test done after 28 days had past. That came back negative, I also had the HIV RNA test done 2 days later and that came back negative but then I later found out it only screened for HIV 1, that freaked me out, So at 46 days I had the Oraquick test done and that came back negative as well but I was still pretty paranoid So i had the HIV RNA 2 test done and I am waiting for these results and I am going absolutely insane, SOO my main questions are, is the p24 antigen present in hiv 2? How conclusive are the results at 28 for the 4th gen test in regards to hiv 2, and how conclusive is the oraquick test at 46 days 6 1/2 weeks?

There are no antigens developed for HIV 2 so my guess is a 4th gen test at 4 weeks if you're concerned about HIV 2 is 95% conclusive (again with regards to HIV2) since only 5% of people take more than 4 weeks to develop antibodies.

**BUT** the risk of contracting HIV 2 outside of Africa is insignificant and you should not worry about HIV 2. Subsequently the risk of actually contracting HIV even with someone positive is low. So the odds are overwhelmingly in your favor (add to that the negative tests)

If you took a 4th gen at 4 weeks then that test is conclusive and you are negative. Dont concern yourself too much about HIV 2.
